JOHN, resident of Fond du Lac,

THOMAS W. YMEIKLEJIOHN, or: Form Dunno, wrsconsnn seamen-annex.

T allwkom it may concern Be it known that I, THOMAS W. Marxiana citizen of the United States, and in the county of Fond du Lac and State of Wisconsin, have invented new and useful Improvements in Service-Trucks, of which the following is a description, reference being had to the accompanyingdrawings, which are a part of this specification.

The invention relates to automobile trucks and more particularly to a truck provided with means for loading and unloading vehicles onto and from the truck.

l Jhile the invention is primarily designed to provide a. service truck for motor tractors so that in case the tractor is disabled and needs repairs necessitating its transportation to the repair shop it may be readily hauled up onto the service truck and carried to the shop, the servicetruck may also be used for transporting other vehicles and machinery or heavy freight.

The invention further consists 1n the several features hereinafter described.

In the drawings: Figure l'is an elevation view of the device embodying the invention,

parts being broken away and parts being shown in section; Fig. is a bottom view of the truck, parts being broken away,

In the drawings, the numeral '3 designates the body of an automobile truck, 4 and 5 the rear wheels, 6 the drive shaft, 8 the rear axle construction including the usual difierential and the wheel drive shafts. V The rear wheel 4 is provided with a drum 9 bolted or-otherwise suitably secured to said wheel so as to turn with it and when in use this wheel is raised by a jack 10 under the axle 8, and the wheel 5 is held against rotation in any suitable manner as by blocks 11, the differential gearing between the rear wheels and the drive shaft permitting the independent movement of either wheel, as will be readily understood.

The platform of the truckis composed of fixed planks 13 and removable planks 14.-

rails or skids, grooves 17 'being provided in the upper faces of said planks to :form

"tracks for the'frontwheels of the tractor or other vehicle where said wheels areiprovided with flanged tread portions as is the case with the Fordson tractor for which this servlce truck is partlcu'larly des1gned.

'VVhen the planks 14 are usedas skids they are braced int-ern'lediate their ends by means of uprlghts 18 provided with hooks 19 detachably eugaginjgsockets 20 in the underside of said planks. When not employed as skids the planks 14 are replaced upon the truck body between the planks 13 to form the truck platform.

The drum 9 receives a. cable 21 which is secured at one end bya hook 22 to one of tally disposed guide pulley 25 mounted in a bracket 26 secured to the truck frame and thence over a horizontally disposed guide pulley 27 mounted in frame supports 28, and from this pulley thecablepasses beyond the truck through a tackle block 29, and thence returns and issecured atits other end by a hook 30 to a staple or anchor 31 medially mounted in one of the truck frame members. The tackle block 29 is provided with a hook 32 engageable with a clevis 33 which is adapted to fit over the draw bar plate on the rear end of the tractor though it will be understood that this tackle block may be secured to the vehicle or load to be moved in any suitable manner.

With this constructiom when it is desired to lift a vehicle, such as a tractor, onto the truck, the planks 14 are placed in inclined position as shown in the drawings, the clevis 33 secured to the tractor and the cable 21 paid out so that the block 29 may be secured to the clevis. The wheel 5 is blocked up and the wheel 4 lifted off the ground by the jack 10. -Then on a forward drive of the shaft 6 the wheel 4 is turned and winds up one end of the cable onto the drum 9 which produces a pull on the clevis 33, as the other end of the cable islsecured't'o" the truck, with the result that the tractor is moved onto the skids 14 and run up on these skids onto the fixed planks 13 of the truck platform, the y described serving. to

guide the cable and keep the tractorin the propelposition during its upward movement on the skids 14:. After the tractor has been hauled up onto the platform of the truck, the cable is unhitched from thetractor, unwound from the drum 9 and unhooked from the wheell. To lower' the tractor from the vehicle the wheels 4 and 5 are held off the ground, the cable attached to the tractor and Wound around the drum and the tractor moved down the skids, the

cable being paid out from the drum and its speed being controlled by applying the usual'vbra-kes to the rear axles, the shaft 6 be ng disconnected from the engine during the unloading operation.

From the foregoing description it will be apparent that the device is of simple construction 2l11ClW8ll'fiClitPllt-3Cl'01 the pur- 7 pose described. 7

J- What I claim as my invention is:'

. l. lira motor truck, the combination, with a truck. body, and one of the rear wheels, of av drum mounted on said wheel, a hauling cable anounted on said drum,

" hook means on the end of the oableadjacent said drum to detachably engage one of the spokes of said wheel means on the truck body for guidingsald cable, a truck plat.-

form including removable floor members .adapted to form a continuous floor for said a with a truck body, adifferential mechanism,

and one of the rear wheels, of a drum fixed on said wheel and in axialalinement therei with, a'vertical guide pulley mountedon the under side of said truck body and disposed above said drum, a horizontal guide pulley [carried by said truck body forward of the vertical guide pulley, a central horizontal guide pulley carried centrally by the truck body rearwardly of saidhorizontal guide pulley, a flexible cable engaged with said drum and having its adjacent end detachably secured to one of the; spokes of said wheel, said cable passing upwardly over saidrvertical guide pulley then forwardly i and around thehorizontal guide pulley andv then rearwardlytoward the center'of the- .truck and engaging the central horizontal:

guide pulley, a tackle block carried by said cable rearwardly of the last mentioned, guide pulley, said cable being'passed forwardly after engagement with the tackle block, means securing the end 'OfSEL'iCl cable remote'from the drum centrally to the "truck I body near the forward end thereof, removable floor members for said truck body and adapted to be disposed rearwardly from the rear end of said truck body to provide an inclined gangway, means detachably securing StHClfiOOIf members to the rear end ofsaid truck body, and brace means for the intermediate portion of said gangway, said tackle blocldbeing adapted to be detachably en- 7 gaged with a vehicleto move the same on to 1 lor off the truck body. v 3

In testimony whereof, I aflix my signature.
